621-21090-01 Specifications and Compatible Tools

Key specs: 3-phase 200V AC power input, 2.5kg payload capacity, 300mm reach, 0.025mm repeatability. Designed for Brooks Reliance 3 (2012–2018 production) and Applied Materials Centura load locks (model 6820, 2014–2020).

Compatibility warning: Do not install on Brooks Reliance 2 platforms (part number 621-21085-01) without upgrading the base controller firmware to v3.2.1. The Reliance 3-specific motor driver (part 621-21120-03) is non-interchangeable.

What to Check Before Buying a Used 621-21090-01 in 2026

Motor encoder resolution: Must read ≥1024 CPR using a Brooks diagnostic tool (model 621-21400-02). <512 CPR indicates degraded feedback.
Wrist joint play: Measure axial runout with a dial gauge (<0.05mm acceptable). >0.1mm correlates with imminent bearing failure.
Robot lifecycle count: Units with >500,000 taught positions (check via Brooks’ RobotLog v2.7 software) show 40% higher teach repeatability errors.
Power supply stability: Use a Fluke 434 II to verify <2% voltage drop under load. >3% signals failing capacitors in the drive module.
Vacuum leak test: Apply 20kPa to end-effector ports; leakage >0.5L/min requires seal replacement (part 621-21150-04).

Q: Does the 621-21090-01 work in 2026-era tools?
A: Yes, but firmware upgrades are required for compatibility with 2024+ Brooks controllers. Check tool specs.

Q: Is 621-21090-01 better than the 621-21090-02?
A: The -02 model (2022 release) adds IP65 sealing but lacks the -01’s 0.025mm repeatability. Use -01 for precision.

Q: Why is the price range so wide?
A: Refurbished units include motor rebuilds and new encoders; used units may need 621-21120-03 drive replacements.

Q: How to verify operational hours?
A: Use Brooks’ RobotLog v2.7 software to pull the hour meter from the robot’s EEPROM.
